Carb setting RRSP

Post by enduro250 »

Using Standard BDST32 carbs:
After the runon on the dyno, I still have the problem that the fuel mixture at the first moment after the opening of the throttle, it is to rich.
I assume that the vacuum slide (no idea what is the correct name) opens too early or too quickly.
The carbs are modified according to the RC SUGO RaceKit Manual,
except the suction spring 3TJ-14933-70
Has anyone an idea what is the diffrence? (stock 3TJ-14933-00)
Or has anyone the spring of the KIT?
Stronger? Softer?
Longer? Shorter?

Look around for a set of secondhand carbs and use them for parts or try them as a set
